Specification of Letters Patent.

Patented June 12, 1917.,

Application led October 2, 1916.. Serial No. 123,287.

To all whom z't may concern.'

Beit known that I, CONRAD T. LENZKE, a 4citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Smoke- Houses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved smoke house adapted for the smoking of sausages, ham, bacon, and the like, and to such ends, generally stated, the invention consists of the novel devices and combinations of' devices hereinafterdescribed and defined in the claims.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

house,

'Referring to the drawings:

Figure 1 1s a vertical section taken through the smoke house on the line 1-1 of Figs. 2 and 3;

Fig. 2 is a front elevation of the smokehouse, some parts being broken away; and

Fig. 3 is a horizontal section taken on the line 3*?) of Fig. 1.

The smokehouse is preferably a rectangular structure, the walls 4 of which are of masonry. This house is provided with large front doors 5, through which the holdirg rack 6 is adapted to be moved when the doors are opened. The rack 6 is hung from atrolley 8, the wheels 7 of which are arranged to run on rails 9. Below its doorway, the front plate of the smokehouse is provided with a large damper 10, and at its top, the smokehouse is provided with. a flue or smoke pipe 11. v

As a medium for producing smoke, erably use sawdust, but other material may be employed. This smoke producing material is placed in a flat shallow sheet metal pan12 that is supported at a distance considerably above the bottom of the smokeby legs or standards 13. This pan 12 is rectangular, but its margin lis terminated inward of the walls of the smokehouse, so as to leave an angular air passage surrounding the pan. As an important feature, this pan is provided with a'langed central heat passage 14 which is preferably in the form I pref-A of an elongated slot extended nearly, but not quite from front to rear of the pan.

Gas is preferably used as a means for heating the pan and this is supplied from a pipe 15 that 1s connected through valve-equipped nozzles 16 to a multiplicity ofperforated burnerpipes 17 that extend into the furnace and are located immediately below the bottom of the pan 12, so that the flames therefromv will be projected ydirectly against the bottom of the pan and produce the required heat for causing the sawdust in the pan to be slowly consumed by an incomplete combus- 4tion producing the smoke.

The nozzles 16, of course, are of a character well known, which take in air to be admixed with the gas. An additional supply of air is delivered below the pan and directly to the passage 14 thereof, through air intake spouts 18 which are extended under the burner pipes 17, `lead from the front of the Y furnace through the front plate thereof and open, one on each side of the said passage 14. y

In previous experiments where the fuel pan had no central passage, it was foundy that articles contained on the central portion of the overlying rack, would not be as thoroughly smoked as the articles on the outer portion thereof, but would cause a sweat and become damp and would not have the proper color. With the central passage and the air delivery spouts or ducts leading thereto, this effect Iis obviated and the articles on the rack will be evenly smoked throughout.

The proper distribution of the smoke throughout the articles on the rack is further made even by means of a multiplicity of socalled spreader bars .19 loosely and movably supported on ledges lor other supports'on the sides of the smokehouse above the rack. By preferably shifting these spreader bars 19, any tendency to form an over-intense draft at any particular point and a much less 111- tense draft at some other point, can be easily overcome.

What I claim is:

1. In a smokehouse, a pan for containing sawdust, or the like, located above the floor of the houseand air passage.

2. In a smokehouse, a pan for containing sawdust, or the like, located above the floor los provlded with a central of the house and provided with a central air l passage, in, combination with' burners located below the bottom of said pan.'

3. In a smokehouse, a pan for contain sawdust, or the like, located above the floor of the house and provided with a central air passage, in 'combination with burners located below the bottom of said pan, and air conduits leading from the atmosphere and terminating adjacent to the central opening ofsaid pan for supplying air thereto.

4. In a smokehouse, a pan for containing sawdust, or the like, located above the floor of thel house and provided with a central air passage, a rack located above said pan, and sprea er bars movably mounted above -said rack.

5. In a smokehouse, a pan for containing sawdust, or the like, located above the iloor of the house and provided with a central air passage, a rack located above said pan, and spreaderbars movably mounted above said rack, the said -smokehouse having a central flue above said'spreader bars.

6. In a smokehouse, a pan for containing sawdust, or the like, located above the floor of the house and provided with a central air passage, in combination with burners located below ,the bottom of said pan, and air conduits leading from the atmosphere and terminating adjacent to the central opening of said pan for supplying air thereto, a rack located above said pan, a multiplicity of spreader bars movably disposed above manana' said rack, said smokehouse having a flue above said spreader bars.;

7 The combination with having a rectangular interior, .of a rectangular pan located above the floor thereof and terminated short of the four walls thereof, said pan havinga central forwardly and rearwardly 'extended central passage, a multiplicity of burner pipes immediately below said pan, a pair of air conduits leading from the atmosphere and delivering below said pan and at the oppositeedges of the central passage thereof.

a smokehouse 8. The combination with a smokehouse A having a rectangular interior, of a rectangular pan located above the floor thereof an terminated short of the four walls thereof, said pan having a central forwardly and rearwardly extended central passage, a multiplicity of burner pipes immediatelyy below said pan, a pair of air conduits leading from the atmosphere and delivering below said pan and at the-op osite edges of the central passage thereo a rack above said pan, and a multiplicity of spreader bars movably mounted above said rack, the said smokehouse having a flue above said spreader bars.

In testimony whereof I allix my signature in presence of two witnesses.
